为什么这个程序不起作用？它返回＆＃34;晚餐＆＃34;对于（12，真）和（7，假），我不明白为什么

Question

def food(var1, var2):
    var2= bool(var2)
    if var1<6:
        food1 = "no food"
    else:
        if (6<var1<11) and (var2==1):
            food1 = "breakfast,marmalade"
        else:
            food1 = "breakfast,coffee"
            if (12<var1<16) and (var2 == 1):
                food1 = "lunch,dessert"
            else:
                food1 = "lunch"
                if (17<var1<22) and (var2 ==1):
                    food1 = "dinner,dessert"
                else:
                    food1 = "dinner"
                    if (22<var1):
                        food1 = "no food"
    return food1

Answer 1

两个输入都落到了最后一个。在第一种情况下你应该有 17＆lt; = var1＆lt; = 22，在第二个你应该有var2 == True
